Delta pyriforme is a species of potter wasp in the subfamily Eumeninae of the family Vespidae. They are distributed across Asia. Several populations are recognized:

• D. p. circinale(Fabricius, 1804)
• D. p. nigrocinctumGiordani Soika, 1993
• D. p. philippinense(Bequaert, 1928)
• D. p. pyriforme(Fabricius, 1775)

Delta pyriforme males have a yellow labrum and clypeus contrasting with the brown body colour. They also have a yellow pronotum and differ from Delta esuriens in lacking a yellow band on the petiole. Delta conoideum lacks yellow on the thorax. ^{[1] [2]}
